After a fuse is replaced
If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacement. (
P. 349)
If the replaced fuse blows again, have the vehicle inspected by your
Scion dealer.
If there is an overload in the circuits
The fuses are designed to blow, protecting the wiring harness from damage.
CAUTION
To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failing to do so may cause damage to the vehicle, and possibly a fire or
injury.
Never use a fuse of a higher amperage rating than that indicated, or use
any other object in place of a fuse.
Always use a genuine Scion fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
Do not modify the fuse or the fuse box.
NOTICE
Before replacing fuses
Have the cause of electrical overload determined and repaired by your Scion
dealer, as soon as possible.

When trouble arises

5-2. Steps to take in an emergency
If the engine will not start
If the engine will not start even though correct starting procedures
are being followed (
P. 165, 169), consider each of the following
points:
The engine will not start even though the starter motor
operates normally.
One of the following may be the cause of the problem:
There may not be sufficient fuel in the vehicle’s tank.
Refuel the vehicle.
The engine may be flooded.
Try to restart the engine again following correct starting proce-
dures. (
P. 165, 169)
There may be a malfunction in the engine immobilizer system.
(
P. 102)
The starter motor turns over slowly, the interior lights and
headlights are dim, or the horn does not sound or sounds at
a low volume.
One of the following may be the cause of the problem:
The battery may be discharged. (
P. 414)
The battery terminal connections may be loose or corroded.
The starter motor does not turn over (vehicles with a smart
key system)
The engine starting system may be malfunctioning due to an
electrical problem such as an open circuit or a blown fuse. How-
ever, an interim measure is available to start the engine.
